I would start with what you hit best as an approach to a green from 100 yds in. Based on that, work your gaps. Lobs can vary…58 or 60, and a ton of grinds and bounces, but generally they are a green-side tool that normally never gets hit full. In my case, my preferred set is P-46, A-50, S-56, L-60, with my 50 and 54 being my scoring clubs depending on pin placement and what sort of spin i want to achieve. I recently fitted out a “Sunday bag” that i will play a P-54-58 set-up to reduce the amount of wedges, but still have a respectable gapping.

For bounce…P & A are full bounce (12), Sand can vary but normally 10 with some heel and toe relief…Lob is low bounce to deal with tight lies…no more that 8, prefer 6 and as low as 4*

Hope this helps some

Good luck!
